Brosnan and de Waal [Nature 425:297-299, 2003] reported that capuchin monkeys responded negatively to unequal reward distributions between themselves and another individual when comparing their own rewards with that of their partner. It was suggested that social emotions provided the underlying motivation for such behavior and that this inequity aversion is specific to the social domain. Howeve...

It has been suggested that inequity aversion is a mechanism that evolved in humans to maximize the pay-offs from engaging in cooperative tasks and to foster long-term cooperative relationships between unrelated individuals. In support of this, evidence of inequity aversion in nonhuman animals has typically been found in species that, like humans, live in complex social groups and demonstrate co...

Abstract Does loss aversion apply to social image concerns? In a laboratory experiment, we first induce in relevant domain, intelligence, through public ranking. second stage, subjects experience change rank and are offered scope for lying improve their final, also publicly reported rank. Subjects who care about decline lie more than those experiencing gains. Moreover, document discontinuity be...

Purpose We conduct a hypothetical dictator game with social distance and time delays using conjoint analysis. Design / methodology / approach Responses from 1,347 Japanese adults are collected through an online survey, and their responses are analyzed using a random parameter logit model. Findings Social preference for the present income of a stranger equals social preference for the income of ...

The effects of kappa opioid receptors (KOR) on motivated behavior are well established based on studies in male rodents, but relatively little is known about the effects of KOR in females. We examined the effects of KOR activation on conditioned place aversion and social interaction in the California mouse (Peromyscus californicus). Important differences were observed in long-term (place aversi...

Agents involved in the formation of a social or economic network typically face uncertainty about the benefits of creating a link. However, the interplay of such uncertainty and risk attitudes has been neglected in the network formation literature. We propose a dynamic network formation model that builds on standard microeconomic concepts of utility maximization, incomplete information, and ris...

This paper briefly and informally surveys different theoretical models of relative concerns and their relation to inequality. Models of inequity aversion in common use in experimental economics imply a negative relation between inequality and happiness. In contrast, empirical studies on happiness typically employ models of relative concerns that assume that increases in others’ income always ha...

This study sought to determine the relationship of job type differences to burnout level, the details of job characteristics for each job type, and the association between burnout and job factors in 189 social workers at all social welfare offices in a prefecture in Japan. Among the three job types, 32.9% of social workers involved with public assistance, 29.0% of social workers involved with p...

Continuous exposure to an aversive mixture was investigated as a means of maintaining aversion to vermeerbos in sheep subjected to the social influence of non-averted sheep. The use of an aversive mixture was based on a hypothesis that continuous exposure to an acceptable aversive mixture (containing both the aversive substance and the identification factors of vermeerbos mixed with maize meal)...

Preterm infants avert their gaze more often and for longer periods in early social interactions compared to full term infants. In previous studies this finding is interpreted as being a function of the higher degree of parental stimulation that is often found in parents of preterm children. The current study explores an additional hypothesis. Since the development of general visual attention ab...
